[MLB-WIRELESS] I've created the 4 nodes for Camberwell on the MW web page

[Me]

Hi all,

I'm thinking out loud and typing at the same time because I'll come along
tonight but want to have a clear direction. So...

I've created the 4 nodes on the MW site. I've put the altitude in for each
node assuming the numbers on the MW map are altitude readings (I'm sure
that's going to make me look really dumb!).

Node 1 = Widey1 = IPT = 70m
Node 2 = Widey2 = IPU = 68m = 0.58km at 168 degrees (South) from Node 1
Node 3 = Widey3 = IPV = 68m = 3.04km at 130 degrees (SE) from Node 1
Node 4 = Widey4 = IPW = 60m = 6.05km at 126 degrees (SE) from Node 1

The above means if all nodes point to node 1, then the antenna (directional
or otherwise) on node 1 needs to cover 42 degrees to reach node 2, 3, and 4.

The other way to look at it is to deal with node 1-->2 as a separate issue
from node 2-->3/4. So:

Node 1 (the highest one being the church), has two directionals on it. One
pointing to node 2 (at 168 degrees) and a second one pointing to node 3 and
4. That second antenna on node 1 only needs to cover 4 degrees to reach node
3, and 4.

IF LOS between node 1/2 and 3/4 is not possible, then Node 3 will have to be
the middle man.

So, the antenna on node 3 would be a 360 waveguide? I don't want to put two
antenna on node 3, but I can on node 1 or 2. I prefer the antenna on node 3
to be inconspicuous so a waveguide / omni is better than a big fat grid
antenna I think. Or maybe people are used to grid antennas? Oh, I don't
know!

I'll see you tonight.

Guy
